a gang bang gone bad, when 4 guys (i: 8 testicles) whip their penises in a circular motion (ie: tornado) around a girl and proceed to ejaculate on her face and/or hair. during the ejaculation phase the 4 guys sing "im walkin' on sunshine wooohooo". during this phase the girl punches each pair of balls so that the four males pass out(ie purple), leaving her the only person standing (ie royale).

"hey man this girl was giving me attitude at the local walmart so i told her i would give her the purple eight ball tornado royale"
